Simple apply online, recruiter called in a couple days, phone screen, 2 - person phone interview. The people seemed nice but I heard some red flags when I was discussing the role such as the kept asking about team members not performing well or fighting and they leaned on that a developer would be better for scrum master without directly saying it. I would have denied the offer as it wasn't for me. Go into this role with caution as seems to be some internal issues going on and they might expect you to do some coding as a scrum master.
